10.6.8 preps for Lion upgrade

Apple has posted Mac OS X 10.6.8, what may be the final major update of Snow Leopard. One of the key features of the code is in fact preparation of the Mac App Store for Mac OS X Lion, which will launch sometime in July. The update is also designed to close several security holes, scrub "known variants" of Mac Defender, and improve VPN reliability as well as support for IPv6 networking.

Fixed is a bug that caused Preview to spontaneously quit. The regular client delta version of 10.6.8 is a 474.2MB download, and requires an existing install of v10.6.7. The combo update, usable by all Snow Leopard client owners, weighs in at 1.09GB. Server editions of the software solve problems with vacation mail notices, Time Machine sharepoints, iCal Server and using Software Update Server. To go with them Apple has posted new Server Admin Tools.

Leopard users can download Security Update 2011-004 in client and server forms. In addition to coping with vulnerabilities addressed by v10.6.8, such as ones with AppleIDs and CoreGraphics, 2011-004 also deals with unique flaws in AirPort, ColorSync and Samba.

    MacBook Pro 13 Early 2011 incompatible with newest

    An updated version of the mach_kernel file (creation date: June 8, 2011) made my MBP shutdown prematurely after applying the MBP Software Update ver1,4 . Restoring the older mach_kernel (March 6 2011) from back-up made everything normal again.
    The 10.6.8 Combo Updater also installs the newer mach_kernel at Root level, and again the MBP would shut down during boot, before the login screen. Safe Boot would let me proceed a couple of minutes beyond login, before the mac would shut down without any error message. No clue in the system log (last entry before shutdown was "BUG found in libdispatch" - hm).
    Again, replacing the mach_kernel file with the older version of which I had kept a copy, cured the problem, and as I am typing this, my MBP has been running without a hitch for almost one hour.
    Another poster at MU (a_w) had similar problems with his MBP 13 Early 2011 after applying the MBP SW 1.4 updater, again with the new mach_kernel file being the culprit.
    Hope this can help anybody having skipped the MBP 2011 software update and experiencing premature shutdowns of their new macbook pro after updating to Snowy 10.6.8.
